Abstract

The utility model relates to a medical device used in orthopedic operation, in particular to a multifunctional sleeve device, which consists of an internal core needle, a sleeve needle and a steel wire guiding elbow pipe. The internal core needle provided with a rotary block pin at the handle bottom is encased by the sleeve needle with a rotary clamping groove at the upper part of the handle. Both handles are provided with vertically penetrated steel wire holes at the same part, and the core needle handle is provided with a transverse steel wire hole. The bottom of the core needle is sleeved by the movable steel wire guiding elbow pipe. The utility model is a novel type assistant device used in orthopedic operation with compound functions, which can shorten operation time, reduce occurrence of systemic inflammatory response syndrome resulting from long-time incision exposure of patient and ease the labor intensity of orthopedic surgeon.

Description

Multi-functional sleeve device

Technical field:

This utility model relates to the medical apparatus and instruments that is used for bone surgery, particularly a kind of multi-functional sleeve device.

Background technology:

At present employed related equipment mostly is the simple function type in the bone surgery, as the vice of using when revolving the strand fixation with steel wire, invar silk two ends unbalance stress often occurs and causes the end phenomenon that fractures, and causes repeatable operation; Use bitbrace or electric drill, in spongy bone such as patella operation, bore the bone passage with guiding steel wire, guiding steel wire etc. during long tubular bone fracture place transverse diameter fixation with steel wire, need the apparatus of multiple simple function to be used alternatingly, not only operation inconvenience, and effect is not good enough, particularly in dark art Yezhong, curved hemostatic forceps aid in guide steel wire in also need using dehisces just can draw steel wire through multi-pass operation often in the position because of being difficult for definite vascular forceps; In treatment fracture delayed union or bone does not connect operation, often cut bone grafting, wound is big, and blood fortune is destroyed heavy.

Summary of the invention:

Goal of the invention of the present utility model provides a kind of alternative existing multiple bone surgery set, integrates hand drill, steel wire guiding, steel wire and revolves the multi-functional sleeve device that straight, the closed bone grafting of strand reason, sled such as dial at function.

The technical scheme that realizes the foregoing invention purpose is: this multi-functional sleeve device is made up of inner core pin, tube pin, steel wire guiding bend pipe three parts, this inner core needle guard is loaded in this pin, inner core pin handle bottom is provided with the rotation bayonet lock, tube pin handle top correspondence is provided with the rotation draw-in groove, two handles are provided with vertical threaded hole of steel of up/down perforation in same area, also be provided with the transverse steel wire hole on the tube pin handle, the active steel wire guiding of tube pin bottom overcoat bend pipe.

The multi-functional sleeve utensil of implementing according to technique scheme has following function:

1, hand drill function: in the spongy bone operation, hold the tube pin and inner core pin handle that combine, determine direction after, can evenly exert oneself, the tube pin was bored spongy bone, guide in order to next step steel wire.

2, steel wire guiding function: after taking out the inner core pin in the tube pin that runs through spongy bone, draw standby along the tube pin steel wire; Fixedly the time, guide bend pipe to be set in a pin bottom on steel wire around the tubular bone fracture place, bend pipe is walked around the bone pipe, and steel wire is drawn standby along a pin and bend pipe.

3, steel wire revolves the straight function of strand reason: vertical, horizontal threaded hole of steel on the handle is passed at aforementioned steel wire two ends of putting on respectively, and tractive can be managed directly.Strand is revolved in tension then, can make the steel wire two ends stressed evenly, and good fixing effect and steel wire do not fracture.

4, closed bone grafting function: under the X line monitors, tube pin and inner core pin are punctured to the fracture line place of disunion, extract the inner core pin, the spongiosa bone mud of getting ready is sent into fracture line by the tube pin get final product.

5, sled is dialled function: when the fracture closed reduction was not good, to determining the position, gripping handle with hands can conveniently dial with sled with the puncture of tube pin.

In sum, this utility model is employed a kind of novel complementary apparatus in the bone surgery process, it integrates the combined type function, can provide convenience for the patient, clipper service, can shorten operating time, reduce the generation of patient's systemic inflammatory response syndrome (SIRS) due to long-time otch exposure, increase work efficiency, alleviate orthopedist's labor intensity.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.The described multi-functional sleeve device of this embodiment is made up of inner core pin 1, tube pin 2, steel wire guiding bend pipe 3 three parts, this inner core pin 1 is set in this pin 2, inner core pin handle 5 bottoms are provided with rotation bayonet lock 8, tube pin handle 4 top correspondences are provided with rotation draw-in groove 9, two handles are provided with vertical threaded hole of steel 6 of up/down perforation in same area, also be provided with transverse steel wire hole 7 on the tube pin handle 4, the active steel wire guiding of tube pin 2 bottom overcoats bend pipe 3.Vertical threaded hole of steel 6 and transverse steel wire hole 7 among this embodiment are provided with four respectively, and the alternate handle both sides that are divided into.

Claims
